TL;DR Masala movie lovers will love it. Would not recommend it to people who liked Tamasha.
I'll be honest. I am a huge SRK fan, and I love any movie where SRK plays himself. That doesn't mean I like all his movies. Movies like Chennai Express and Happy New Year were just about average. That being said, I loved this movie. The movie was not billed as anything else except for a paisa-vasool entertainer and it delivers. You have these grand locations, glitzy costumes, and great cars. More importantly, the screenplay is quite racy and in spite of way too many convenient plot twists, doesn't make you yawn.
The performances were great. Not artistic, just entertaining. Rohit Shetty cashed in on the SRK-Kajol romance to good effect. Shahrukh was Shahrukh, Kajol was a little too bright (literally), Varun Dhawan was hilarious in parts, and Kriti Sanon was gorgeous. My only complaint with the movie was a couple of sequences involving Johnny Lever in the second half.
The action set pieces are Shetty-esque and the music by Pritam was really catchy (must've been "inspired" by some really good albums). Overall, I would definitely recommend this film if you want to put everything behind you and laugh out loud for a couple of hours. If you expect this movie to make you think about how you can solve the world's problems, you are clearly not familiar with Rohit Shetty's work.
Pros: Shahrukh, Varun Dhawan's comedy, great visuals, catchy songs, one plot twist and high entertainment factor
Cons: A couple of comedy sequences in the second half
